Janet sells erasers at a price of $8$ erasers for $60$ cents. She started this table to show the price for different numbers of erasers. 

1. Complete her table.

   Step 1 (a):

   Set up a proportion to help you fill in the table.

   $\frac{8}{0.60}=\frac{4}{\textit{x}}$

   Step 2 (a):

   Solve for $x$.

   Answer (a):

   	Erasers	$8$	$4$	$1$	$12$	$10$	$16$	$100$
   	$\$$	$0.60$	${\color{red}{\mathbf{0.30}}}$

   Use the same method to fill in the rest of the table.

2. Does this situation represent a proportional relationship? Why or why not?

   Hint (b):

   Look at the values you found for the table.
   Are the different values related? If they are, how are they related?
   Does this tell you if they are proportional?

3. Use the information in the table to find the cost of $144$ erasers. Write and solve a proportion, if appropriate.

   Hint (c):

   Use the same method as part a to find the cost of $144$ erasers.
